NIDA Clinical Trial Requesting Volunteers for Learning Tasks

You may be eligible for a research study.


The National Institute on Drug Abuse (NIDA) is looking for volunteers to participate in a study which seeks to find out if performance in learning specific tasks differs in people who have an opioid-use disorder and those who don’t. This study requires one lab visit which would last around five hours.


Eligibility for the study:

  • Between ages of 21 and 60

  • Willing to fast at least six hours prior to the session and smell food odors

  • If you have an opioid-use disorder

    • Be abstinent for three weeks or

    • Be in methadone or buprenorphine treatment

  • Can’t be intoxicated at the time of session

  • Can’t be pregnant


Layout of the study:

  • Participants will give a urine and breath test.

  • Participants will be given tests of learning such as looking at a computer screen with shapes which are paired with food odors. Afterwards participants will be given a shape and asked which odor to expect.

  • 30 and 60 days later, participants will be called and asked about their drug use over the last 30 days.


This study is free to join and compensation is provided for time and travel. To learn more call 1-800-535-8254.
